why isn't it healing

L
I walked around 6 miles from work to my house and I felt fine except for the fact that my vagina was burning... when I came home my husband and I had sex and it felt like I had a paper cut down there.. my husband then checked and found two small cuts in the entrance of my vagina so he searched it up and it said it was caused because of the friction of walking so much so now it's been around three days of just letting it heal and staying away from sex and it's still there. Does anyone know how to help me heal faster or what the hell to do because it still hurts like a bitch when I wipe.
